--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
IPEHR: 0xfffff080

it ate some garbage that is I suspect the scratch address for a pipecontrol.

HEAD:  0x0000243c

is well advanced into the ring, and has not yet wrapped, so unlikely a bug in
ringbuffer management.

Yet it ended up seeing a corrupt command stream. Mysteries.
